ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R07-OAR-2017-0517; FRL 9971-05-Region 7]


State of Iowa; Withdrawal of Direct Final Rule; Elements of the 
Infrastructure SIP Requirements for the 2012 Annual Fine Particulate 
Matter (PM2.5) National Ambient Air Quality Standard (NAAQS)

AGENCY: Environmental Protection Agency (EPA).

ACTION: Withdrawal of direct final rule.

-----------------------------------------------------------------------

SUMMARY: Due to an adverse comment, the Environmental Protection Agency 
(EPA) is withdrawing the direct final rule for ``Approval of 
Implementation Plans; State of Iowa; Elements of the Infrastructure SIP 
Requirements for the 2012 Annual Fine Particulate Matter 
(PM2.5) National Ambient Air Quality Standard (NAAQS)'' 
published in the Federal Register on September 29, 2017. Infrastructure 
SIPs address the applicable requirements of Clean Air Act (CAA) section 
110, which requires that each state adopt and submit a SIP for the 
implementation, maintenance, and enforcement of each new or revised 
NAAQS promulgated by the EPA. These SIPs are commonly referred to as 
``infrastructure'' SIPs. The infrastructure requirements are designed 
to ensure that the structural components of each state's air quality 
management program are adequate to meet the state's responsibilities 
under the CAA.

DATES: The direct final rule published at 82 FR 45479, September 29, 
2017, is withdrawn effective November 20, 2017.

FOR FURTHER INFORMATION CONTACT: Heather Hamilton, Environmental 
Protection Agency, Air Planning and Development Branch, 11201 Renner 
Boulevard, Lenexa, Kansas 66219 at (913) 551-7039, or by email at 
[email protected].

SUPPLEMENTARY INFORMATION: Due to an adverse comment, EPA is 
withdrawing the direct final rule to approve revisions to the Iowa 
State Implementation Plan (SIP). In the direct final rule published on 
September 29, 2017, (82 FR 45479), we stated that if we received 
adverse comment by October 30, 2017, the rule would be withdrawn and 
not take effect. EPA received an adverse comment. EPA will address the 
comment in a subsequent final action based upon the proposed action 
also published on September 29, 2017 (82 FR 45550). EPA will not 
institute a second comment period on this action.
